Randy is starting a beehive so that he can have fresh honey. He decides to check the current population of bees in the hive by m

satela [25.4K]

Answer:

Best estimate for the bee population is 1280.

Step-by-step explanation:

Randy marked total number of bees = 160

Then he collected 240 bees and observed that number of bees marked

= 30

We have to find the total population of the bee or best estimate for the bee population.

Now we use the ratio of marked bees in the sample vs marked bees in the total population

$\frac{\text{Number of bees marked in the sample}}{\text{Total bees in the sample taken}}=\frac{\text{Number of bees marked in total population}}{\text{Number of bees in the hive}}$ $\frac{30}{240}=\frac{160}{x}$

x = $\frac{160\times 240}{30}=1280$

Therefore, the best estimate for the bee population is 1280.

Expand

ddd [48]

Answer:

The working of expressions is shown below.

Step-by-step explanation:

We are given the following information:

a) Expand

$3(x+4)\\3\times x + 3\times 4\\3x + 12$

b) Expand and simplify

$4(x+5)-2(x-3)\\=(4x + 20) -(2x-6)\\=( 4x-2x) + (20 + 6)\\= 2x + 26\\=2(x +13)$

c) Expand

$(x+2)(x+7)\\=x\times x + x\times 7 + 2\times x + 2\times 7\\= x^2 + 7x + 2x + 14\\=x^2 + 9x +14$

d) Factorize fully

$12x-18\\=6(2x-3)$
